Abstract: This fourth subvolume presents data on the geometric parameters (internuclear distances, bond angles, dihedral angles of internal rotation etc) of free polyatomic molecules including free radicals and molecular ions. The survey on structure data consists of four subvolumes, each containing the geometric parameters determined in the gas phase either by an analysis of the rotational constants (and sometimes the vibrational constants) obtained from microwave, infrared, Raman, electronic and photoelectron spectroscopy or by an analysis of electron diffraction intensities. Most of the structures listed in the tables are for molecules in the electronic ground state, but structures for electronically excited states have also been included as far as they are available. In this fourth subvolume, the structure of molecules containing five to sixty carbon atoms is listed.

RefComment: Supplement and Revised Editon to II/16

Abstract: The volume II/27 has been divided into three subvolumes according to the classes of compounds: Subvolume A: Diamagnetic susceptibility and magnetic anisotropy of inorganic and organometallic compounds; Subvolume B: Diamagnetic susceptibility of organic compounds, oils, paraffins and polyethylenes; Subvolume C: Diamagnetic susceptibility and magnetic anisotropy of organic compounds. The data presented in this volume are based on the literature survey of the chemical abstracts up to 2005. The calculated values of diamagnetic susceptibility of organic compounds in the present subvolume II/27B are presented along with their experimental values. They have been calculated with the use of structural parameters in structural formula by using different theoretical methods available in the literature.

RefComment: Supplement and Revised Editon to II/16

Abstract: The volume II/27 has been divided into three subvolumes according to the classes of compounds: Subvolume A: Diamagnetic susceptibility and magnetic anisotropy of inorganic and organometallic compounds; Subvolume B: Diamagnetic susceptibility of organic compounds (Part 1); Subvolume C: Diamagnetic susceptibility and magnetic anisotropy of organic compounds (Part 2). The data presented in this volume are based on the literature survey of the chemical abstracts up to 2005.

Abstract: For more than 1000 luminescent organic substances the most important data are represented as wave numbers of absorption and emission bands, decay times and quantum efficiencies. Additional tables contain further information for restricted groups of substances (figures on typical spectra, wave numbers of sharp single bands, influence of surrounding molecules, etc.).

Abstract: Photoelectron spectroscopy has matured considerably during the last decade. The experimental techniques were improved markedly. Photon line sources and,in particular, synchrotron radiation sources are now routinely available in many places. The volume summarizes data on the bulk electronic structure of solids. Besides the photoelectron results, a limited set of other data (such as lattice constants and work functions) useful in the context of band structure information is presented.

Abstract: Some years after the publication of Vol. III/11 and its supplement III/18 dealing with elastic, piezoelectric, pyroelectric and optical properties of crystals, a complete recompilation of the data of these volumes and of new data was performed. Because of the growth of this subject matter it was found convenient to divide the material into four volumes, III/29a and b for the low frequency properties and III/30a and b for high frequency propertiesof dielectric crystals. The first subvolume III/29a contains exclusively second and higher order elastic constants including temperature and pressure coefficients.

Abstract: While vols. III/29 A, B (published in 1992 and 1993, respectively) contains the low frequency properties of dielectric crystals, in vol. III/30 the high frequency or optical properties are compiled. While the first subvolume 30 A contains piezooptic and elastooptic constants, linear and quadratic electrooptic constants and their temperature coefficients, and relevant refractive indices, the present subvolume 30 B covers second and third order nonlinear optical susceptibilities. For the reader's convenience an alphabetical formula index and an alphabetical index of chemical, mineralogical and technical names for all substances of volumes 29 A, B and 30 A, B are included.

Abstract: This new volume of Landolt-Börnstein consits of two subvolumes. A on Diffusion in Semiconductors and B on Diffusion in Non-Metallic Solides. This separation was necessary, because the field and the number of data is too large to be compressed into a single volume only. This separation - we hope - also reflects the expected difference in the interets of potential users.

Abstract: Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, orient by a magnetic field, and absorb characteristic frequencies in the radiofrequency part of the spectrum. The spectral lines of the nuclei are highly influenced by the chemical environment i.e. the structure and interaction of the molecules. NMR is now the leading technique and a powerful tool for the investigation of the structure and interaction of molecules. The present Landolt-Börnstein volume III/35 Nuclear Magnetic Resonance (NMR) Data is therefore of major interest to all scientists and engineers who intend to use NMR to study the structure and the binding of molecules. Volume III/35 "NMR-Data" is divided into several subvolumes and parts. Subvolume III/35A contains the nuclei 11B and 31P, subvolume III/35B contains the nuclei 19F and 15N, subvolume III/35C contains the nucleus 1H, subvolume III/35D contains the nucleus 13C, subvolume III/35E contains the nucleus 17O, and subvolume III/35G contains the nucleus 77Se. More nuclei will be presented later.

Abstract: Volume III/38 Optical Constants provides critically evaluated data on refractive indices of inorganic and organic liquids and their wavelength dependence (dispension). Part A contains the inorganic, organometallic, and organononmetallic liquids, and the binary liquid mixtures (about 900 pure substances and their mixtures). Part B contains data of more than 7600 organic liquids.

Abstract: Vols. III/17a-i and III/22a, b (supplement) on semiconductor physics and technology have been published earlier, the latter covering new data on the technologically important group IV elements and III-V, II-VI and I-VII compounds only. The wealth of further data from the last decade is now being critically evaluated by over 30 well-known experts in the field of semiconductors. To meet the demands of todays scientists and to offer a complete overview on semiconductor data all data available so far are published in the following way: a series of five subvolumes covers only the supplementary data to volumes III/17 and 22.

Abstract: Volume III/5 offers a compitation as complete as possible of the space groups and lattice con-stants of all crystals which have been studied by means of X-rays, neutron and electron diffraction.

Abstract: This volume is a compilation of vapor–liquid equilibrium data on subcritical binary single-phase or two-phase liquid–liquid systems. All the components are well-defined pure substances, which are organic or inorganic nonelectrolytes, including low-melting ionic liquids and water. The present database contains numerical data for 3316 systems. The book reproduces in tables and graphs the numerical values for only 802 binary mixtures, chosen to be representative of all the compound classes and property types. The full set of data is given on the CD–ROM accompanying the book. Most data files contain experimental data compiled from the original literature published from 1929 to mid 2006. The CD-ROM displays all these data in PDF format and in fully documented computer readable standard electronic files (SELF and ELDATA). The ELBT-program allows the fast search of data according to property type, chemical system, author(s), source and year of publication. It also includes the bibliographical database of ELDATA, EVLM’2006, giving 13471 references from 1888 through mid 2006 to experimental vapor–liquid equilibrium in mixtures and solution.

Abstract: Diffusion – defined as mass, amount, or particle transport process – is the most essential transport property besides viscosity and thermal conductivity. Diffusion is widely used in nature, technical and scientific applications, ranging from diffusion in all kinds of gases, liquids, solids, electrolytes and their mixtures. Due to the large amount of data, the volume LB IV/15 "Diffusion in Gases, Liquids, and Electrolytes" is divided into three subvolumes. Part A: Gases in Gases, Liquids and their Mixtures; Part B: Liquids in Liquids and Liquid Mixtures; Part C: Ions and Electrolytes in Liquids, Electrolytes and Molten Salts. The presented subvolume A includes the main chapters Measurement Methods, Diffusion in Pure Gases, Diffusion in Gaseous Mixtures, Diffusion of Gas/Vapor in Gases or Liquids and Diffusion of Gases in Solution. Due to the very different and widespread measurement methods, a precise description of these methods is given.

Abstract: Volume IV/1 contains information on the densities of liquid systems. It may be considered as a supplement to volume II/1 of the 6th Edition, which contains only a few data on nonaqueous systems. Data are not listed for all systems but primarily for those of greater interest where data for a larger range of concentrations were available.
